What are the requirements for the safe distance of the cable line?
Control cable is to control the use of electricity, the compensation cable is power-assisted. I just literally understand t to know which industry you know bfjn
The wires are long and the voltage will drop, and the wires are resistive, although the wires are made of copper and aluminum with a low resistivity, but the resistance of the wires can not be counted. If the resistance of the wires is one ohm, The current is 10A. Then the voltage drop on the wire is 10V. With 220V power supply. Call the electrical device at both ends is 210V. So long-distance transmission to use high pressure. If the distance is not long thick copper wire can be used to reduce the voltage drop
BVV line refers to the copper core plastic sheath line; BV wire refers to the copper core PVC insulated wire. BV - bare copper wire, often wear pipe, bridge laying. BVV - jacket line, often apply. BV line referred to as plastic copper wire, name, general purpose single core hard conductor without sheath power cable. B represents the category, cloth wire, T represents the conductor: copper conductor, V represents the insulation is: polyvinyl chloride. Applicable to AC voltage 450 / 750V and below power plants, household appliances, instrumentation and telecommunications equipment with the cable wire.
